xen0n added a comment.

From a LoongArch developer's perspective, it may be better to only enable UAL 
for LA464 and other supporting models, instead of for the generic `loongarch64` 
model too. This is because although all server- and desktop-class LoongArch 
models have UAL, the embedded-class (Loongson-1 and Loongson-2 series' older 
models) doesn't, and some of them e.g. Loongson 2K1000LA are readily available 
on the market so they're arguably relevant. We don't want to generate 
misaligned memory accesses for those systems only to fall back to much slower 
emulation later.
